Application filed February 28, 1924. ficrial No. 695,654;

To all to 7mm z''mcg concern:

Be it knowntliat' I, HUGO Tonontninrnn,

a citizen of the United States, residing at Newark, in the county ofEssex and Fit-ate of New Jersey, have invented lie-wand usefulImprovements in Bag-Frame Locks, of

which the v-iollowing is a specification This invention relates toimprovementsin key actuated locks-- in which a bolt clement is movedrelative to its tee-per by suitable manipulation of a key, types ofwhich are commonly and widely known, that-selected for illustration:being a conventional bag frame lock.

One of the objects of the invention is to provide-a fined longitudinalmember within the body of the look, through. which the bit andstem ofthe key passes, guiding the key its entire length, preventing it frombecoining misplaced or entangled and also from being turned prematurely.

Another purposeis to produce a key guide that tends to prevent the useof an improper key and by the use of which the usual fixed guide pin orpost may be dispensed with and the consequent drilling of the key stem,

A. further aim is in the provision of a key guiding device whichoperates to strengthen and re=enforce the lock casing, particularly theextending portion thereof which is frequently subject to blows andcollisions with other objects.

WVith these and other analogous aims and objects in View, the inventionconsists in the novel construction and arrangement of parts hereinafterdescribed and shown in the annexed drawing, forming a material part ofthis disclosure, and in which Figure 1 is a perspective view of a lockas assembled on the frame of a bag.

Figure 2 is a sectional view in perspective, showing the interior of thelock and drawn to an enlarged scale.

Figure 3 is a transverse sectional view taken on line 3-3 of Figure 2.

Figure i is a partial end elevational and central vertical sectionalView of the same.

Figure 5 is a view similar to Figure 2, but showing a modification inwhich the key guide post is omitted.

Referring more in detail to the drawing, the numeral 10 designates ingeneral the main portion of the lock casing, the same having outstandingend flanges 11 on one side to provide meansfol-securing thelb'ck rigidlyon the part to which'itis applied;

In the upper portion ofth'eiront wail of the casingare openings 12adapted to receive keepers (not shown) the" same being engageafble bybolts 13 operable within the casing.

On the top wall ofitlie casing is lined the 1 flanges of a hollowupstanding guide bracket 14, open at both ends, theinner of whichregisters with an opening of corresponding dimensions-in the topwalli'ot' t'he casing. y

Movable in this opening and extending normally past the bracket 14, towhich it'is neatly fitted, is a. hollow'bolt' release slide 15, itsouter end wall containinga-key entrance opening 16.

The lcweren'd or this Sines animus raised member 17 ot a plate f8rigidly fixed on" a correspondingplate 19 and having between them anintermediate plate 20 containing a key hole 21, the lowermost plate V19having a; central lowered portion 22.:

Fixed in this elementl'22'is'a' post 23 extending upward in registerwith: the key holes 21' and 16 and adapted to enterthe openingQd in theshank or stem of the key by pins, not shown, operating in the openings28.

From the foregoing it will be seen. that a key with a relatively longstem or shank is used, the entering end of which must be accuratelyguided, and more particularly if 7 no post is used, as illustrated inFigure 5.

In order to provide an eflicient guide for the keys of such locks andwhich will per niit the omission of the post, and consequent drilling ofthe key stem, a guide tube 30 having lateral flanges 31 to suit the wardoi the key the stem 25 of which fits the tube is inserted between theupper wall of the side 15 anda plate 29 fixed at the lower end at theslide;

This guide tube 30 is held in position by flanged partitions 32 and 33fixed transversely in the slide and which positively directs the passageof an entered key from the escuteheon 16 to' the key hole 21 renderingit impossible to enter the key at an angle, to allow it to becomeentangled and which permits dispensing with the post.

Furthermore the construction very materially re-enforces the extendingportion of the lock, subject to accidental injury as it is, besidesproviding means for entering a key in a convenient and proper manner. 7

It will be understood that the application of a key guide tube is by nomeans limited to bag frame looks but is equally applicable to a widerange of lock types in which a key is used having a Ward or bitextending from its cylindrical shank or stem. 7

WVhile certain preferred embodiments of this device have been shown anddescribed, it will be understood that changes in the form, arrangements,proportions, sizes and details thereof may be made without departingfrom the scope of the invention as defined inthe appended claims.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent, is

1. A key operated bag lock comprising a casing, a slidem'ovable'transversely therein, a bolt movable in saiu casing, a. key foractuating said bolt, and an unbroken key guide fixed in said slideextending longitudinally from the key entrance opening to the plane ofapplication of the key' to said bolt.

2. A key operated bag lock comprising a casing having a central raisedslide movable therein, a bolt movable in said casing, a key foractuating said bolt, an integral key guide tube fixed in said slideextending longitudinally from the key entrance opening to the plane ofapplication of the key to said bolt, and lateral flanges on said tubeadapted to engage the bit of said key therebetween.

3. A key operated lock comprising in combination with a casing, a boltmovable in said casing, and a key for actuating said belt, of an opensided key guide tube fixed in said casing extending longitudinally fromthe key entrance opening to the plane of application of the key to saidbolt, lateral 1 application, and transverse elements in said sliderigidly supporting said tube.

5. A look comprising a casing, a bracket extending thereabove, two ormore plates united to form a bar movable in said casing in the plane ofsaid bracket, a covered slide having a key entrance fixed to said bar, atubular key guide of unbroken length fixed in said slide below theentrance to extend the full length thereof, and means earried by saidbar to prevent a spurious key from turning therein.

This specification signed and witnessed this 25th day of February, 1924.
